A Quote by Sy Montgomery

The fact that three-fifths of an octopus' neurons are not in their brain, but in their arms, suggests that each arm has a mind of its own.

Octopuses have hundreds of suckers, each one equipped with its own ganglion with thousands of neurons. These 'mini-brains' are interconnected, making for a widely distributed nervous system. That is why a severed octopus arm may crawl on its own and even pick up food.

There are 100 billion neurons in the adult human brain, and each neuron makes something like 1,000 to 10,000 contacts with other neurons in the brain. Based on this, people have calculated that the number of permutations and combinations of brain activity exceeds the number of elementary particles in the universe.

Vilayanur S. Ramachandran

There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.

Tim Berners-Lee

The mind is its own enemy, that fights itself with the innumerable pliant and ineluctable arms of the octopus.

The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.

Michio Kaku

The brain immediately confronts us with its great complexity. The human brain weighs only three to four pounds but contains about 100 billion neurons.

Unlike the heart or kidney, which have a small, defined set of cell types, we still do not have a taxonomy of neurons, and neuroscientists still argue whether specific types of neurons are unique to humans. But there is no disputing that neurons are only about 10 percent of the cells in the human brain.

What is left over if I subtract the fact that my arms goes up from the fact that I raise my arm?

Ludwig Wittgenstein

It's better to be an octopus than a fish. If an octopus loses a tentacle to a predator, the octopus will survive with seven tentacles left for itself.

Gene Simmons

Most of the different types of cells in our body die and are replaced every few weeks or months. However, neurons, the primary cell of the nervous system, do not multiply (for the most part) after we are born. That means that the majority of the neurons in your brain today are as old as you are. This longevity of the neurons partially accounts for why we feel pretty much the same on the inside at the age of 10 as we do at age 30 or 77.

The brain immediately confronts us with its great complexity. The human brain weighs only three to four pounds but contains about 100 billion neurons. Although that extraordinary number is of the same order of magnitude as the number of stars in the Milky Way, it cannot account for the complexity of the brain. The liver probably contains 100 million cells, but 1,000 livers do not add up to a rich inner life.

Gerald Fischbach

What has three heads, six arms, and half a brain?" Three asked. One and Two answered in unison. "Nate Sutter.

Brandon Mull

A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.

David Eagleman

Blacks have no rights - in fact they were three - fifths human according to the constitution to give slave owners more voting rights. So that's African Americans.

Noam Chomsky

Modern brain-scan technology has revealed that each person shapes a completely unique brain. Other studies have documented the amazing regenerative ability of the brain, which can be reshaped by the power of your mind to bring you the world you desire. Knowing that, the obvious question arose: Why not use your mind to create the brain you want, using conscious choice?
